17Source code layout:
18
19build/          - build directory (created by make).
20math/           - math subproject sources.
21math/include/   - math library public headers.
22math/test/      - math test and benchmark related sources.
23math/tools/     - tools used for designing the algorithms.
24networking/     - networking subproject sources.
25networking/include/ - networking library public headers.
26networking/test/ - networking test and benchmark related sources.
27string/         - string routines subproject sources.
28string/include/ - string library public headers.
29string/test/    - string test and benchmark related sources.
30pl/...          - separately maintained performance library code.

32The steps to build the target libraries and run the tests:
33
34cp config.mk.dist config.mk
35# edit config.mk if necessary ...
36make
37make check
38
39Or building outside of the source directory:
40
41ln -s path/to/src/Makefile Makefile
42cp path/to/src/config.mk.dist config.mk
43echo 'srcdir = path/to/src' >> config.mk
44# further edits to config.mk
45make
46make check
47
48Or building and testing the math subproject only:
49
50make all-math
51make check-math
52
53The test system requires libmpfr and libmpc.
54For example on debian linux they can be installed as:
55
56sudo apt-get install libmpfr-dev libmpc-dev
57
58For cross build, CROSS_COMPILE should be set in config.mk and EMULATOR
59should be set for cross testing (e.g. using qemu-user or remote access
60to a target machine), see the examples in config.mk.dist.
